T0 ALL WHOM IT MA-Y CONCERN:4

Be it known that I,REUBEN S. WHETHER, of Dorchester, in the county of Norfolk, and State of Massachusetts, have invented certain new and useful Improvements in Window-Screens, ot' which the following is a full, clearg'and exact description, reference being had to the accompanying drawings, making part of this speciication, infwhich- Figur represents the outside of a portion'iof an ordinary window having my improvements applied thereto; Figure 2, an inside view of the same, the screen having been detached from the sill and carried up by the roll.

Figure 4, a vertical transverse section, on the line A. B of figs. l or 3. Figure 5 is a central longitudinal section of Athe screen-roll, thespring-shaft, and bushings, and of the end plates, which formsupports for the roll.

Figure 6 is a back side view. of the case containing the roll, but detached from the window, the roll being'y shown as supported by the plates at the ends of the former; showing, also, the slotted spring-plates which con.- nect the case and the roll with the lower rail of the sash.

Figure 'T is a bottom side view of what is shown in fig. 6..

Figure 8 is an end elevationv of iig. 6, and

' This invention relates to that class of window-screens, the special object of .which is to exclude mosquitoes and other insects from enclosures, while admitting as much as possible the circulation of air through the screen, which covers an open space.

The objects of this invention are- First, simplicity'and economy in the construction of the self-winding roll, and in the application of the shaft and the spring to the end of the roll. t

Second, protection of the screen and: the roll in stormy or rainy weather.

Third, more perfectly covering the aperture or opening below the raised windowfsash.

Fourth, greater convenience in attaching the case and the roll to the'sasb, and the lower end'of the screen to the window-sill, and of detaching the same at pleasure.

Fifth, to provide a rolling window-screen, which, when the sash is raised, may be easily drawn down and attached to thefwindowsill, and detached from the sill or its lower connection by simply lowering or closing .the sash;

i necting and holding-devices, e, when arranged relatively to the This invention consists- First, in the construction and combination ofthe parte which form the self-winding roll, A, the same being composed of the shaft, B, bushings, C and D, spiralrspring,`E, the disk, F, and the' body, A, of the roll.

Second, in thc case or cover, G, when applied to the sash so as to protect the screen and the roll, and, in

combination with the case or cover,.of a slotted plate, a, and a concave plate, b, as' supports for the roll, and A for other objects hereinafter described.

Third, my invention consists in the peculiar arrangement and combination of the roll, screen, and case with the-sash and the window-frame, whereby the screen is made to more perfectly cofver the open space after the sash` is raised, and that the lowerend of the screen may be disconnected from the sill .by simplylowering or olosingfthe sash.

Fourth, my invention consists in the slotted curved spring-plates d applied to the case Gr, and arranged to connect with screws c, or holding-devices, projecting from the sash. v

Fifth, my invention consists of the slotted plates f, applied to the bar H, in combination with the conbevelled side, g, of the case, so as to detach the latter bar from the holding-devices, and allow the screen to. rise by simply closing orlowcring the sash.

Sacos 2 .In constructing and applying my improved window-screen, I iirst take an ordinary roll, squared at both endsLand of asuitable length,and in one end `a hole is bored about six inches deep. At the inner end of this hole, and against the solid substance of the wood, I place a metal disk, F, and against this disk a bushing, C, which serves as a bearing for the` shaft B, the inner end of which bears against the disk.

The roll may turn on the bushing, or the bushing may turn on the shaft. A

A spiral spring, E, winds around the shaft B, to furnishV the power for turning the roll to wind up the screen.

One end of the spring is attached to the inner end of the shaft B, and th'e opposite end, l2, is bent back, and secured in a groove made in the outside of a bushing, D, which forms a bearing for the outer end of the shaft. i This -latter bushing is fastened to the roll proper, and the shaft fits. loosely within it.

` The extreme end of the shaft is square, and fits in a square bearing in the endplate a, (see figs. 5 and`9,) so that the roll may turn in either direction, to wind up the screen or allow it to unroll without turning the shaft; for, as it will be seen, confining one end of .the shaft is necessary, in order to bring the power ofthe spring into action 'to turn the roll, and wind up the screen when detached from the sill, M, or the holdingdevices, e. y i

The plate a, at or about its centre, and around the square shai`t-bearing, isconcave on the outside and convexon 'the inside. This allows of greater length of the square shaftbearing and'of bearing-surface, to 'accommodate any endwise motion of tle shaft or the roll, without having the outer end of` the shaft come in contact with the pulley-stile, L, when the sash, K, and the ease and roll are raised or lowered, lwhich is of some importance.

The opposite end of the roll A is supported by a plate, b, both of the plates a and b being fastened to and flush with the ends of the sloping top, g, of the case4 G. l

The plate b is slotted from its lower end upward to near the central bearing-screw l: This admits of the screen being removed frofn the roll, or replaced therein, without detaching the plate or disconnecting the roll from the case, therol'l being grooved longitudinally, to receive the 'topend'of'the screen, in the usual way.

Tlie lower end of tlr'e screen may be attached to the bottom bar, H, in the same, or in any convenient The bearing-screw lis intended to regulate the action of the roll, operated by or against th'e action of the spring, by tightening or loosening said screw, and thereby increasing or diminishing the friction between the end of the roll and the inner surface of the plate b. v

To the inner edge, 3, of the top portion,I J, of the case which covers the roll, slotted curved spring-plates d are secured, and screws c, or other connecting and holding-devices project from the outside of the sash. yThe case is connected with the inner sash by sliding it downward in the space occupied by the outer sash,- the curved spring-forks n of the plates d passing each side of the screws c, and underor back ofthe screw-heads, thus connecting the case with the sash, the spring-forks drawing and holding the parts closely together.

The case and the rollmay .be detached 'from the sash by sliding them upward, aslthe yielding action ofthe v spring-forks allows of their being easily removed or replaced.

After the case and the roll havebeen connected with or attached to the sash,'as described, the screen is drawn downward by the hand laying hold ofthe bar H', the lower side of said bar is brought down on to the top of the sill M, and then slid outward over the screws e, which rise from` the sill. The shouldered sides m` of the slotted platesfpassing beneath the heads ofthe screws connects this bar and thelower end of the screen with'- the sill.

This improved screen may be disconnected from the sill by sliding the bar H back a little, and allowing the screen to wind upon the roll without moving the sash. 0r if, by reason of a change in the weather; or for any other reason; it should be desired to close the window, simply sliding the sash downto the sill brings the inner lev'el of the lower edge of the portion g of the Acase into contact with the outer` edge of thebar H, and slides said barinwad, releasing the shoulders m of the plates f from, the heads of the screws e, and detaching l 'thebar H and lower end ofthe screen fromA the sill.

This mode ot' detaching the screen I consider,veryl'important, for it leaves the windowavailable for observation at either side as well as directly forward, or as a passage for articles in the day-time, or when the screen need not be drawn over the open space. And it is my intention to detach the lower end of the screen and allow it to roll up whenever the window is closed, or whenever desired, without lowering the sash, thus making the rolling window-screen att'achable to and detachable from the sil-lor the holding-devices, at the pleasure of the user, anddetachable by closing Aorllowering the sash, as described.

It will be observed that when'" the sash is raised, and the screen S is nnrolled and drawn downward, the extreme sides of such screen lie fair against the inner sides or surfaces of the outside casings N, and thereby cover more perfectly the. open space, and moreleiectually exclude mosquitos and other insects.

Theba'r H has transverse grooves, O, seenin figs. 1 and 4, which allow said bar to-slide forward over thue heads ev of the screwsy rising from the sill, and the plates f to slide underthem, or inthe opposite direction, to detach the bar and the screen from the sill. i

When the case, roll, and screen are applied asv shown and described, andthe sash is closed, the roll and A screen are well protected by the case, which {its the outside of the sash, and closes tight down on the top of the sill, keeping the screenand the roll dry. A v vI am aware that rolling window-screens have been used, the roll operated by a coil or a spiral spring, and that auch screens have been rendered intachableand detachable, by bolts at the ends' of the lower bar, and by a hook or several rings, to connect the top of the screenl to the sash.

.I am also aware that a rolling screen has been made to cover the opening produced by raising the sash.

I disclaim having invented veither of the above devices or improvements; but What I do claim, and desire to secure by'Letters Patent, is'y 1. The combination and arrangement of the 'shaft B, bushings C and D, disk F, and spring E, with the body A of the roll, in the manneruand for the purpose specified. Y

2. The plate a, provided with a concave bearing, in combination with the square-ended shaft B and its connections, and with the case G, for the purpose and substantially as described.

3. lThe plate b, provided with a slot, p, when used in combination with the roll A, and with the case G and `the screen S, for the purpose and substantially as described.

4. The curved spring-plates d, slotted as shown and described, in combination with the case G and the screws cor holding-devices, which connect the case and the roll with the sash, as described.

5. The slotted plates f, constructed as described, in combination with the. bar H and the screws e, for theV purpose and substantially as described.

6. The combination, with the sash K, of a case, G, constructed vas described, the case-serving as a CoverV and protection to the roll andthe screen, and also as a device for detaching the bar H and the s creen from the sill, for the purpose and substantially as described.

7. The arrangement and combination of the roll, screen, and case, and the supporting-plates, with the sash, and the bar H with the sill M, so that the screen shall more perfectly cover the open space produced by raising* the sash, as and for the purpose set forth.

8. The combination of all the operative parts specified, arranged to operate substantially as and'for the purpose set forth.
